I just finished reading two books.
The Dilbert Principle by Scott Adams. I vaguely remember reading this book during undergrad (I'm not sure I really did though, there was just so much Dilbert floating around during undergrad.) Of course, reading a book like this after getting a full-time job is a completely different experience. Geeks can relate.
Microserfs by Douglas Coupland. This chronicles the lives of a couple of geeks working for Microsoft during the early Nineties. A frankly accurate portrayal of geek life, this was probably the first book in ages that I didn't feel like putting down. Geeks can relate.
Both are recommended.
